Document Type and Number:
WIPO Patent Application WO/2021/157745
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a lubricant composition that can substitute for chemical processing using a phosphate, the lubricant composition being provided with stable lubricating performance in a practical manner without the need for extra steps, and of providing a method for forming a lubrication coating using the lubricant composition, and a metal workpiece in which the lubrication coating is formed on the surface thereof. As a means for solving the abovementioned problem, the present invention provides a lubricant composition for forming a hemimorphite-containing lubrication coating, the lubricant composition containing water-soluble zinc and a silicic acid compound (e.g., colloidal silica) in a solution.
